Canteens and catering businesses prepare and serve food for people at workplaces, schools, colleges, hospitals and other organisations, as well as for private and public events. Canteens may operate on site, offering meals and refreshments for customers to eat in or take away. Menus can include breakfasts, hot lunches, sandwiches, salads, snacks and drinks, with service ranging from a staffed counter to a full dining area. Catering services may provide food for meetings, celebrations, conferences and other gatherings. Depending on the arrangement, they can plan menus, prepare and deliver meals, set up serving areas and provide staff, crockery or equipment. Customers may be able to request options such as vegetarian, vegan, halal or allergen-aware dishes. Businesses in this category vary in scale and may provide regular meal services under contract, one-off event catering, or both.
